IssueRSA ClearTrust, Inter-Site Single Sign-On (ISSO), and Platform for Privacy Preferences (P3P) Initiative
ResolutionThe RSA ClearTrust Installation Guide gives instructions on how to configure Inter-Site Single Sign-On (ISSO). It only briefly mentions that ISSO is achieved by setting a third-party domain cookie. Many browsers require configuration changes to allow the setting of third-party cookies. Asking users to modify these settings is often undesirable; an alternative is to implement the technologies defined by the Platform for Privacy Preferences (P3P) Initiative. P3P is a set of standards being developed by the World Wide Web Consortium (W3C) for handling all aspects of a web site's privacy policy.

One aspect of a privacy policy covers how the web site uses local and third-party cookies. A correctly implemented privacy policy will allow users with conforming browsers (Internet Explorer 6.0 and Netscape 7.0) to navigate across ISSO without modifying their browser settings. Recommendations on how to define and deploy a privacy policy is beyond the scope of this document. Details about the P3P standard and other useful links can be found at http://www.w3.org/P3P/.
